The chefs will collaborate on a six-course dinner, matched to wines served in large-format bottles (thus the Imperial name; an Imperial bottle holds the equivalent of eight standard bottles).

Limber up those dialing fingers, because only 90 tickets will be sold, available only by calling Boka (312-337-6070) directly. Tickets are $165, excluding tax and tip (with tax and tip, it'll be closer to $215).
